IMPROVEMENT IN CARDlNG-ENGINES.

Specieation forming part of Letters Patent No. l 8,257, dated September 22, 1857.

T0 all whom it may concern.-

Be it known that we, VILLIAM H. VAL- TON, of the city of Brooklyn, county of Kings, and State of New York, and GEORGE Il. PHINNEY, of the city, county, and State of New York, have invented new and useful Improvements in Oarding-Machin es for Carding \Vool, Cotton, Silk, Flax, and other Textile Substances; and we do hereby declare that the following is a full and exact description thereof, reference being made to the accompanying drawing, which is a vertical longitudinal section of our machine, and also to the letters of reference marked thereon.

The nature ot' our invention consists in the use of a cylinder-brush arranged with alever in such a Inanner as to oscillate to and from the main cylinder, for the purpose of cleaning the same.

The construction of our machine is as follows: The position of the main carding-cylinder and the doffer and the construction of them are the same as they are on the ordi'- nary cards now in use. The cotton passes int-o the machine in usual former' a lap. As it enters, it passes from the rollers a a to the feed-rollers l) h', and it is there taken by the lickers-in c c. These rollers work, as shown by the direction of the arrows, so that when in motion they come in contact with the lickers-in d d. The teeth on the bekers-in d d work against the cotton on the lickers-in c c', and thereby take the lumps, sticks, dirt, che., from the cotton, together with a portion of the saine from the lickcrs-in c c. The lickers-in d d run, as shown, by the direction of the arrows and thereby. come in contact with the knives or bars 'i i 'L' and t" t" t" t. The knives are stationary and can be regulated as desired by set-screws attached to them. The knives being` set close to the lickers-in will cut and break off the sticks, dirt, dic., that come in Contact. The lickers-in c e and d d. are stripped by the main cylinder e, which carries the cotton to the doffer in the usual way. Yhile the main cylinder is carrying the cotton from the lickers-in to the doffer it comes in contact with the roller h, Which straightens out the fibers and carries the loose ones back to the licker-in c, which repass through the machine, as before introduced.

Then the main cylinder has run sufficient time to lill the teeth, it is necessary to strip it, which is generally done by hand, although there are several inventions for stripping; but they as yet have not come into general use, some on account of having to obtain too high speed, which cannot be obtained from the machinewith advantage. Some are connected with too many obstructions for practical use. Others are too complicated to admit of their bein g broughtin to use in any manner. Therefore our object is to facilitate this operation to a great advantage to manufacturers in the following manner: \Ve apply a rotary brush H, which is iixed on lever K. The lever K, being fixed on the stud I, will oscillate when put in motion by the hand or foot, so that when the teeth of the main cylinder have to be stripped or cleaned the driving-belt that gives motion to the main cylinder when in operation is removed to the loose pulley. This being done, the main cylinder-will gradually decrease in speed until it stops 3 but previously to its stopping, when at a low speed, the operator can apply his hand or foot on the lever K, which will raise the brush ll against the main cylinder to any depth required in the teeth, and also put the wheel 3 (shown bythe blue lines) in gear with wheel 4, (also shown by the blue lines,) which is xed on the lickerin d', which gives a higher speed to the brush l1 than the Inain cylinder. Therefore the brush H cleans out the refuse and cotton accumulated in the teeth of the main cylinder and deposits it on the comb L, which is fixed on the lever K. The strip pings are taken away from under the card at the operators leisure.

vhat we claim as ou r invention, and desire to secure by Letters Patent, is-

The application and use of a rotary brush.

for stripping the Inain cylinder, in combination with the lever K, or its equivalent, by which the Inain cylinder is stripped and cleaned when ruiming at the speed given by shifting the driving-beltl from the driving-pulley to the loose pulley, as fully described and shown in the specitication,for the purposes set forth.
